Never allocate more personal capital to this sector than you can afford to lose. This is as speculative and risky as it gets.
Forget about the investment amount in the beginning because you have to make your investment successful so as you are able enough to look for higher steps but in the start you should try your best for getting success. After you done with successful investments with any profit then it is relevant later to upgrade to higher steps.
Remember that it is not something easy here and you will have to struggle here as well but this is easier than any other investment source in the modern world.
